No Musicthebee, just reconfigure HeavyMetal.
Reset your laptop's video resolution to 800x600. Load Xlobby on the laptop. Enter the Xlobby setup and go to the skins section. Select the 800x600 preset then click save. Xlobby will reconfigure the skin to 800x600 then restart. You can now play around with the skin's screens to make sure everything is sized and placed where you want it. Add a short prefix to all the screen names to distinguish the 800x600 screens from the server's 940x540 screens (ie change menu to Smenu [S is for Simpad!]) Transfer these new Simpad 800x600 client screens over to your server's HeavyMetal skin folder.
You will now have 2 unique client screens in your HM skin folder: one with the ppc prefix and one with the S prefix. Ofcourse, your server screens will have been configured for 960x540.
You will next need to add new goto commands in the event manager (ie. "goto Smenu") or else your client will goto the server screens instead of the Simpad screens. Make sure the startup screen in your Simpad "servers" text file is for "Smenu" not "menu".
Don't forget to change back the display settings on your laptop to 1024x768 when you are done! You can now use the same process to customize client skins for your laptop client screens (ie. Lmenu) in the 1024x768 resolution. Transfer these screens over to your server and you will now have 3 distinct client screens.
Have at it!
